FOLDED PAPER FOR CARPET-LINING, 86C.

SPECIFICATION forming part of Letters Patent No. 379,571, dated March20, 1888.

Application led March 31, 1887. Serial No. 233,216.

To all whom, it may concern:

Be it known that I, AUSTIN GIBB, a subject of the Queen of GreatBritain, residing at Beloit, in the county ofRock and State ofWisconsin, have invented a certain new and useful Improvement in FoldedPaper for Carpet-Lining and other Purposes, which is fully set ferth inthe following specification, reference being had to the accompanyingdrawings, in which- Figure l represents a plan of a section offoldedpaper embodying my invention; Fig. 2, a bottom plan of the same withfastening-strip added; Fig. 3, a section of the same,takeu on the line ll of Fig. l; Figa, a detail perspective of the same on an enlargedscale; and Fig. 5, a similar perspective showing a modificacation in thefolds, also on the same enlarged scale.

My invention relates to folded straw-board, paper felt,or other papersufficiently stiff and heavy for carpet-lining and other purposes.

The object is to produce an article which will possess a` certain amountof elasticity in a vertical direction, which quality will be retained bytbe nature of the folds. The improved paper,when used as acarpet-lining, will also eifectually gather in its folds all dust whichpasses through the carpet, and may be provided with a thin lining orlinings which can be easily stripped to remove, after wear, the dirtwhich has accumulated, leaving the main body for further use.

I will proceed to describe the construction and operation of myinvention as I have carried it out in practical form, and will thenpoint out definitely in claims the special im proveniente which Ibelieve to be new and wish to protect by Letters Patent.

In the drawings,\zA represents astrip of strawboard or thick paper ofany description. This strip is folded transversely by making creases orbends a and a across the strip, one end being in an opposite directionto the other. The direetion of the bends or folds is also alternated.Commencing at the right of the strip shown in Fig. 3 of the drawings,the first fold is to the right and downward and the second is to theleft and downward. The next two folds are in the same direction; but itwill be seen that thereby a right and left fold of each pair are broughtopposite to each other, on one side (No model.)

the folds being turned outward from each other and on the other inwardtoward each other. It will be seen that there will be thus produced afolded strip the folds of which are so arranged as to produce a kind ofbox-plait.

Certain sections, c2, of the paper will remain in a horizontal position,but facing on oppo site sides of the sheet, and certain other sections,a, will stand between the horizontal scctions and connect them together.These latter sections, in the folding process, are crimped or forcedunder the others, so that they stand in a position more or lessinclined', as seen in Fig. 3 of the drawings.A .'Preferably the sectionsor `folds a? are considerably wider than the connecting sections orfolds c3. These folds are considerably elastic, so much so, in fact,that it is impossible to press the folded sheet down perfectly flat andhave it retain this position. Owing to the inclination of thesectionsathe folds may be pressed'down upon each other; but as soon asrelieved from pressure they will open more or less, thereby separatingagain the horizontal sections orfolds a2. I have submitted a web ofpaper-board thus folded to an enormous pressure under an eX-ceedingly-heavy roller or a` powerful press, and with the result thatthe folds would open, as described, as soon asthe pressure was removed.Paper thus folded becomes, therefore, a very desirable carpet-lining, asit affords an-elastic support to the carpet, thereby relieving the wearupon the latter, and also furnishing a soft elastic tread.

If it is desired to increase the elasticity of the lining under thecarpet, two or moresheets of the folded paper may be used, one laidabove the other.

In addition to the elasticity afforded for the carpet, as describedabove, the paper lining folded in this manner also provides large widereceptacles for the dust, which will almost all find its way into thespaces between each two of the upperplane surfaces. The carpet willtherefore be kept cleaner than with ordinary lining. If at any time acarpet is taken up and the lining is not yet worn out, it may berelieved from the dust very easily by proper light shaking or by rollingup the lining and shaking from end of the roll. I have, however, deviseda better Way for effecting the IOU cleaning, which consists in providingone or more sheets, B, of very thin paper, which are laid uponthe mainlining A before folding, so as to be folded with the latter, as shown inFig. 4 ofthe drawings. Now, if the lining is provided with one or moreof these thin coverings, whenever the carpet is taken up the uppermostcovering may be stripped off, thus leaving a perfectly'clean liningunderneath,

upon which the carpet may be relaid. Ihave shown in Fig. 4 of thedrawings two thin coveringsheets, one of which is raised at one end,showing how it may be stripped off without destroying the layersunderneath.

It may be desirable in some cases to hold the folds from any spreading,and lto e'ect this narrow strips of paper, C, or other material may bepasted to the under side of the folded web,runninglengthwisethereof.Thesestrips may be used as desired, and arranged to suit the purposerequired, and fastened to the main web in any suitable way. They mayalso be applied to the upper side of the lining, if desired, orto bothsides if there should be any occasion for such use.

In order to produce this article of folded paper,I have found itnecessary to devise a new machine, as I could find no machine forfolding paper or other material which would produce the articledescribed above. This new machine, however, does not constitute a partof the present invention, and need not be described in this connection.It will furnish the subject-matter for another application for patent.

The material which I have described and -shown herein has been spoken ofespecially therefore, as limiting this folded paper to carpet-lining,for I propose to apply it to various other purposes to which I may findit adapted.

In Fig. 5 of the drawings I have'shown a modification'in the folding bywhich the results which I have described above may be obtained in ameasurable degree, but not to the full extent as when folded as alreadydescribed. In this modification there is buta single bend,first in onedirection and then in the other, something like an S. The sheet D showsno horizontal sections, but long inclines d, with short sections, d,connecting each two of these and bent under slightly, so as to standsomewhat in clined from a perpendicular themselves. The paper folded inthis way will have something of the elastic action of that shown inFigs. 3 and 4 of the drawings, but not to the same eX- tent. In each ofthe Figs. 3, 4, and 5, E represents a flooring upon which thelining islaid.

Having thusdescribed my invention, whatI claing as new, and desire tosecure by Letters Patent, is-

l. A carpet-lining composed of a strip of paper-board, A, or other likematerial, bent or crimped, as described, to produce elastic folds, andone or more unattached and removable strips, B, of thinner paper, foldedwith the thick sheet A, but readily separable therefrom, substantiallyas and for the purposes specified.

2. In a carpetlining, a strip ofpaper-board, A, or other likemateriahfolded as described, in combination with one or more unattachedsheets of thinner paper, B, foldedtherewith but readily detachabletherefrom, and tyingstrips C, secured to the back of the main strip A,substantially as and for the purposes specied.
